Sofia Vergara is usually seen dressed to the nines with a full face of glamorous make-up.

But the actress decided to poke fun and her usually perfect look when she appeared on the Ellen DeGeneres show.

The two CoverGirls joined forces to take part in a hilarious comedy skit that was written by the chat show host.

Face-painting: A comedy skit on the Ellen DeGeneres show saw Sofia Vergara covered in make-up

Teamwork: The ladies teamed up to promote CoverGirl cosmetics, a brand they both work for

And the performance also served to promote the brand and its new product, for which they star together in the commercial.

Ellen, 53, stood behind Sofia, 39, who was wearing a wide-sleeved yellow and pink kimono with her hands behind her back.

The host then replaced Sofia's arms with her own and applied an enormous amount make-up to Sofia's face while the actress read from Ellen's script.

She splashed water on Sofia's face before piling foundation, powder, eyeshadow and lipstick all over her.

'Sometimes, just for fun, I like to put it on my nose,' Sofia said while Ellen spread CoverGirl products all over her face.

While she started out with a series of protests, the Colombian born TV star then began to give direction to Ellen, who remained hidden behind Sofia.

'That's not eyeshadow!' she protested as she was doused with powder.

Good sport: Sofia was happy to make fun of herself during the sequence

Powerless: Ellen took control of Sofia's arms for the performance

'My cheeks look better with as much rouge as possible in the cheeks. Rouge in the forehead,' she instructed Ellen who spread blusher over her face with a large brush.

And I put between my breasts a little bit,' she added as Ellen crunched a whole pot of eyeshadown into the star's ample clevage, which saw Sofia lose focus for a moment because she was chuckling so much.

Despite her protests, Sofia was a great sport throughout the whole sequence and could barely contain her laughter.
